LUBRIGATR.

Application filed October 23, 1924. Serial No. 745.412. i

My v'invention belongs to that general class ot devices known as lubricators, and relates more particularly to a lubricator or oil' cup particularly adapted .tor use on vehicles such as automobiles or the like, although the saine may be used Wherever satisfactory. The invention has among its objects the production of 'a lubricator oi the lrind described which is` simple, convenient, compact, attractive, eliicient and satisfactory for use Wherever toundapplif cable. lt has among itsturther objects thel production ot a torce `:teed lubricatoi which maybe easily manipulated as desired. Many other objects and advantages oitfthe' kkcon struction herein shovvn'and described'will be obvious to those skilled in the art trom' the disclosures herein given. y A

To this end my invention consists in the novel construction, arrangement and combination and parts herein shown and described, and more particularly pointed out in the claims. f

In the drawings, wherein like reference characters indicate like lor corresponding parts: l

Fig. 1 is a sectionalvieiv through my improved type ot lubricator;

, Fig. 2 is a sectional view taken substantially online 22 of Figjl; and j f Fig. 3 is a sectional view of a portion ot the lubricator, `illustrating a slightlymodi-v iied top construction. V `Reterring to the davvings, in which the j'ireferred -embodimentot the invention is shown, 1 represents a shell or container of the desiredl size, shape and material, pro-A vided With a stemy or shankv 2 `arranged vfor attachment tothe part to be lubricated', for example it may be threaded asshorvn, and having a discharge port or outlet 3 at` the end. rlhe shell is provided `ivi'th an offset or outstanding beaded yportions1 arranged to provide a chamber or recess 5 in the cup when the valve or plunger is .in position. The valvek or plunger `consists ot a cup'- shaped member consistingot the bottom k7 and side Walls arranged to :tit in the cup and slide therein. the same constitutinga combined plunger and valve. The plunger provided with oneorl more openings 11 about the same, communicating Withfthe space 5 and normally is maintained in the position shown in Fig. 1 by a spring 12 orv its equivalent. y

A plate orbar 13 connected with the plunger is arranged to cooperate with the spring 12 which engages Withthe flange 6 or its equivalent at the top ot the cup. Ar-

ranged on the cup is a cap 14 which is profy vidcdwith a flange 15 at the-edge and pret- Verably depressed or odset, as indicated, at

the center. Betweenthe plate 13 and the ycover plate 14 is a rod or connectingmeinber 17, the same engaging with the supplemental spring 18 arrangedonA thecap. Genen yallyjI 4prefer to provide a gasket or Washer y 19, as indicated; Cap 14 maybe provided with an outstanding portion 2O arranged toengage with the turned-over flange 22 on a tofpv cover part Q1, Which covers the spring 18and end vof the rod 17.y j

The `cup may be filled with oil or lubricant or otherinaterial which it isv desired to teed by lifting or tilting thel top and ,dis-k charging thereunder into Ythe cup and plungl er. vunder the plunger d'oivn `:through and out Any lubricant in chamber` 5 can iiovv past the outlet 3vr When 'the plunger is so raised, lubricant also flowing th'rtnigh` the openings 11 into and` filling the chamber 5. Obviously, as the, plunger is lifted, this causes al suction under the plunger, tend- `ingtosuck the oil trom chamber 5 below so ,that when the plunger returns', it then tends totorce feed the oilfbeloiv the plung er through theport 3 tothe point to be lubricrated. "When there is sufficient oil in the cup, that is, when' it -doesnot need replenishing. the part to be liibricated may be eas? ily lubricated by merely flipping up the n cover and lett-ing itdrop' baclr. the voilbeing discharged downtlhrough the 'port 3` as previously described. This may be continn ucd until the cup is empty, it not being nec- U essary to put oil in the cup everyT time. yThe device is therefore particularly7 convenient for use on automobiles or the'like. Owing to the construction-oi the device'.A itis not onliT possible to inaleithe `samevery compact and simple, but it willbe'lilrorvise noted that the same cannot be easily talren apart and tampered With` so that it i salvvays prop.- crly 'assembled and cannot get out ot order or become disarranged. The spring -lSis designed to maintain the cover tightly seat'- o ed; on the casing 1,`that isyit is maintained lseated yunder tension and consequently will not rattle and bey noisy. Likewise being maintained firmly' in` place except when raised inoperating the plunger, there is no leakage ot the oil between the cup and cover when the device is subjected to jars and vibration. There is no possibility of the cup being left open either through forgetfulness or because the cap or cover has been lost or mislaid. f

The construction shown in Fig. 3 is substantially similar, except in this case the cover plate 25 is not provided with a recess but the part 26 is formed with an upstanding chamber portion Q7 in which is arrangeda .spring Y29 which bears against the head 30 on the rod Q8. ln this particular form, it is not necessary to litt the cap as merely lifting the rod 28 will cause the valve to be opened. This type ot device may be refilled or the oil replenished by lifting the cap similar to the other construction mentioned. ln this form the cover is always maintained seated except whenlifted to operate the plunger. f

ln both constructions, the part to be lubricated is efficiently lubricated, due to the pressure on the oil caused by the return of the plunger. The device may be operated without dilliculty and without soiling the hands. `When applied to an automobile, it is a comparatively easy matter to go over the car and merely flip up the covers or lift on the head 30, using a screw driver or the like, and the automobile may be eiliciently lubricated in but a few moments time. There is nothing to rattle or work loose, or to become mislaid.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination oi parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:
